According to the WHO, the circulating poliovirus type 3 (cVDPV3) has been detected in three environmental samples in the arrondissement of Cayenne since May 2024. No cases of acute flaccid paralysis or polio in humans have been detected. The last case of wild poliovirus in French Guiana occurred in 1983; cVDPV had not previously been detected.
While further information is pending, in addition to the basic immunization against polio, a booster vaccination is recommended for:
- immunocompetent travellers <65 years: every 20 years
- immunocompetent travellers ≥65 years: every 10 years
- travellers with immunodeficiency: every 10 years
